Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021488, here are decompositions:

5 + 1021483 = 1021488
31 + 1021457 = 1021488
47 + 1021441 = 1021488
59 + 1021429 = 1021488
71 + 1021417 = 1021488
101 + 1021387 = 1021488
107 + 1021381 = 1021488
157 + 1021331 = 1021488

Showing the first eight; more decompositions exist.
